could be spectra, technora or a Kevlar blend, they would have strength in the same range as amsteel. Ditto price.
This is something I don't have. So now I want it.
Please don't sell any of it to me... no matter how much I beg.

the chain of West Marine stores sometimes have it.
I went in and asked for some 1/8 Amsteel and the guy asked me: "What do you need that for? To lift up the front end of your car?"
Plenty of places on line to get it, and you know what you are getting.
Try some of the ones here on the forum like Dutch, Arrowhead Equipment, etc.
Just for your future information...Zing It is normally found at arborist supply stores. It was developed as a throw line.
Get a weight-weenies scale and measure the 30 ft of it. Fiber strength is proportional to the mass of it (roughly +-10%). And some of this is coating, which has much less strength.
Weigh and report it. Divide by .3 and we'll know the weight per 100ft, which can be compared to that of other rated UHMWPE lines.
There is a recent SK-91 fiber which is nominally stronger than SK-75 used in Amsteel Blue. But, I think its significant improvement is a reduction in creep.
Color makes me think of the Vectran V12 I picked up for whoopie slings at WestMarine. I couldn't find it more expensive, or closer. It is smaller than Amsteel blue 12strand (which is half the price). 3 strands = 9mm.
West Marine says 1900 lbs, the manufacturer says 2100. I figure it'll hold me fine! Very little stretch once the splices take their set too. Stiff enough to not tangle easily and easy to splice.
Oh yeah, they have PDFs for different splices if you're interested.
